Biography

Sostre was born in Harlem NY on March 20, 1923 to parents Crescencia and Saturnino Sostre. His mother was a seamstress, and his father a merchant marine. After being drafted into the Army in 1942, he was dishonorably discharged.

In 1952, he was arrested for possession of heroin and sentenced to 12 years in prison. He served time at Sing Sing, Attica prison and Clinton State Prison. During his incarceration he began to study Islam, and was placed in solitary confinement for trying to start an Islamic study group. He had saved up to start the shop by working for Bethlehem Steel.The store became a center for radical thought and education in Buffalo's Black community. He stocked the shelves with books on the subjects of Communism, anarchism, and black nationalism, as well as jazz records, making it a popular hangout for young leftists.

After a series of race-related riots in the Cold Springs neighborhood where the Afro-Asian Book Shop was located, a neighboring tavern caught fire and many of the store's books were destroyed by the water the firefighters used to put it out. Of Sostre's charges: and the key witness used in the trial later recanted his testimony.

Incarcerated once again, Sostre was this time placed at the Green Haven Correctional Facility in Dutchess County. Once there, he refused to submit to rectal examinations or to cut his beard, and was again placed in punitive solitary confinement.

Sostre was placed in solitary confinement for more than 5 years.

In December 1973 Amnesty International put Sostre on its "prisoner of conscience" list, stating: "We became convinced that Martin Sostre has been the victim of an international miscarriage of justice because of his political beliefs ... not for his crimes ." In addition to numerous defense committees in New York State, a Committee to Free Martin Sostre, made up of prominent citizens, joined in an effort to publicize Sostre's case and to petition the New York Governor Hugh Carey for his release. On December 7, 1975, Russian Nobel Peace Laureate Andrei Sakharov added his name to the clemency appeal. Governor Carey granted Sostre clemency on Christmas Eve of 1975; after receiving appeals from Ramsey Clark, Phillip Berrigan, Daniel Berrigan, Rev. Ralph D. Abernathy, Julian Bond and Angela Davis.

Legacy

Black anarchist writer and activist Lorenzo Kom'boa Ervin attributes his initial interest in anarchism to Sostre.

In 1974, Pacific Street Films debuted a short documentary film on Sostre called Frame-up! The Imprisonment of Martin Sostre detailing Sostre's case with in-prison interviews.

In 2012, activist Mariame Kaba lamented the lack of biographies on Sostre.

In November 2017, the Frank E. Merriweather Jr. Library hosted To and From 1967: A Rebellion with Martin Sostre, an event commemorating the 50th anniversary of the Black rebellion on Buffalo's East side. The event included an installation created by a local eastside artist called Reviving Sostre. The installation consisted of three bookshelves painted by the artists and placed in the lobby of the Merriweather Library, which was built on the same location one of Sostre's bookstores used to stand.

In 2019, four years after his death, the New York Times published an obituary of Sostre in their "Overlooked No More" series, "obituaries about remarkable people whose deaths ... went unreported in The Times" and intended to include people from marginalized backgrounds whose profiles had not been included.

The Martin Sostre Institute maintains a website that includes an archive of Sostre's writings, photos and films about Sostre, and information about court cases in which he was involved. In March 2023, the Institute co-hosted a birthday centennial celebration for Sostre alongside the New York Public Library's Jail & Prison Services team, the NYPL's Harry Belafonte Library, and the Schomburg Center for Research in Black Culture.
